Share.

Knowledge isn't like a cheeseburger. If I have a cheeseburger and I want to share it with someone, I'll have less for myself. Knowledge doesn't work that way. You can share knowledge as much as you want, and you won't lose any of it.  There's no good reason to be selfish with knowledge -- that's exactly why everyone should be teaching in some capacity. Share what you know.
